the present study performed to examine canola meal on morphology of thyroid gland in broiler chicks. in this experiment 300 l-day-old unsexed ross broiler chicks assigned into 5 groups. the chicks were fed by five level of canola meal (0, 5, 10, 15 and 20%). after 42 days feeding four chicks from each pen killed and their thyroid glands removed and immediately were immersed in formaldehyde, bef...

ABSTRACT: The purpose of this research was to study the histology and describe microscopy findings epididymis epithelium greater Rhea americana at three time periods: November 2005 (n=14), December 2006 (n= 20), May 2007 observe compare differences that occurred. We studied from 54 rheas, bred in Santa Maria, Rio Grande do Sul, Brazil. were collected during commercial slaughter fixed bouin. Opt...

The possible in vivo role of TGF-beta 1 in regulating various proteins of the extracellular matrix, including fibronectin, collagen I and III, and glycosaminoglycans, was examined by immunohistochemical methods during critical stages of lung morphogenesis in the 11- to 18-day-old mouse embryo. Sections of Bouin-fixed, paraffin-embedded whole embryos were exposed to polyclonal antibodies specifi...

The novel pituitary protein 7B2 has a widespread distribution in neurons and paraneurons and is known to be associated with endocrine disorders. In the mammalian lung, solitary neuroendocrine cells (NECs) and their innervated aggregates, termed neuroepithelial bodies (NEBs), are scattered along the bronchopulmonary tree; however, presence of 7B2 in these structures has not previously been repor...

SUMMARY The ?M6 1799 Bouin earthquake is considered as one of the largest earthquakes to have struck Western France. However, seismogenic source potentially responsible for this event remain marginally documented. We present results from a focused offshore-onshore multidisciplinary survey in its meizoseismal area order identify fault segments that ruptured during earthquake. Based on macroseism...

BACKGROUND The intestinal interpositions are important in various operations of the digestive tract. However, they are capable to produce serious immediate and late complications. AIM To compare clinical and surgical outcomes, as well as intestinal pathological findings, in dogs submitted to jejunum and colon interposition. METHODS Forty male mongreal dogs were immunized and dewormed, betwe...

Malignant fibrous histiocytoma is a very aggressive sarcoma. After the tumor has disseminated, chemotherapy is of little influence on the course of the disease because of the resistance to most chemotherapy regimens. We evaluated by immunohistochemistry the prognostic influence of the expression of a member of the stress polypeptides family, the heat-shock protein of 27 KDa (HSP-27). HSP-27 was...

Problem statement: The digestive tract of animals including rodents has taxonomic and ecologic importance due to its ability in adaptation for different environments. Whereas colon absorbs water and carbohydrates, it has a vital role ecologically and physiologically and enjoys different histological structures in different rodents with various diets. Approach: Different rodent specimens belong ...

BACKGROUND, AIM, AND SCOPE In this study, a suite of sublethal stress biomarkers were analyzed in juveniles of the sentinel species, the Pacific oyster Crassostrea gigas, with a view to using them as pollution monitoring tools. The aim of this work was (1) to study baseline seasonal variations of biomarkers in different body compartments of C. gigas in the reference site and, after selecting bi...

The immunohistochemical techniques known as EnVision trade mark + System (EVS) and Mirror Image Complementary Antibody (MICA) were recently introduced into laboratory practice because of their high sensitivity. In this paper these techniques were compared and their sequences combined to obtain a new method possibly more sensitive than the original ones. The immunohistochemical staining employin...
